Per your inquiry in our EXCELLENT DOOM METAL GROUP, RIGHT HERE ON MUSIC BANTER....
Check out the album 'Trouble', by the band Trouble. One of the pioneers of the genre, and their self-titled is easily their best. I'd love to know what you think of it. I think it's a pretty accessible doom album for someone starting out their exploration of the genre, not so trudging and their guitarist is a master. Plus... vocalist is very Halford-esque, something pretty unique in doom.
